Determine Servers Security Posture Goals
Implementation Effort: Medium
Security and IT teams must define baseline security expectations, align with compliance frameworks, and configure Defender for Servers to monitor and improve posture across environments.
User Impact: Low
Security posture goals are defined and managed by administrators and security teams; end users are not directly involved.
Overview
Determining security posture goals in Microsoft Defender for Servers involves setting clear objectives for how secure your server workloads should be across Azure, AWS, GCP, and on-premises environments. These goals guide how Defender for Servers is configured and used to reduce risk, improve compliance, and respond to threats.
Key Objectives
- Reduce security risk by identifying and remediating misconfigurations and vulnerabilities.
- Protect against real-time threats using Microsoft Defender for Endpoint and other integrated tools.
- Align with compliance standards such as CIS, NIST, and Microsoft Cloud Security Benchmark (MCSB).
- Ensure visibility and coverage across all server workloads, including hybrid and multicloud environments 1 2.
How Defender for Servers Supports These Goals
- Provides actionable recommendations to improve machine configurations.
- Enables vulnerability scanning, file integrity monitoring, and just-in-time access.
- Integrates with Azure Arc to onboard non-Azure machines and apply consistent policies.
- Offers agentless scanning and guest configuration to assess posture without performance impact 1.
Planning Considerations
- Choose the appropriate Defender for Servers plan (Plan 1 or Plan 2) based on your goals.
- Define deployment scope (subscription-wide or resource-specific).
- Use Log Analytics workspaces and Azure Monitor Agent to collect and analyze telemetry.
- Regularly review coverage dashboards and resource health pages to track progress 1.
Failing to define and monitor security posture goals can lead to inconsistent protection, compliance gaps, and increased exposure to threats. This capability supports the "Assume Breach" and "Verify Explicitly" principles of Zero Trust by ensuring continuous assessment and improvement of server security.
